Any help on this issue would be greatly appreciated, because we're pretty much stumped. We are within an Intranet, and trying to migrate a heavily used application from CF8 to CF9. We are running a VMWare environment, Windows 2003. The application makes heavy use of CFPDF to generate PDF forms that are used as part of the business process. As such, the application tends to be thread intensive. After tweaking our JVM under CF8, making SQL efficiency changes, and streamlining our process, it has been running on a CF8 physical server with no problems for well over a year. When we tried to migrate the application to CF9 on a virtual server, it bombed. Even with just me testing, our admins watched as the CPU utilization went through the roof almost immediately. Attempts to emulate the same settings on CF9 as we had on CF8 didn't help. So, in an attempt to get some idea what was happening, we set up another virtual server, this time with CF8. No problem in CPU spikes, and the CF8 virtual version is actually running fine in the production environment.
Does anyone have any ideas what might have changed in CF9 (or better yet, something that we are overlooking) that could cause spikes in CPU utilization? Memory utilization appears fine in server monitor, so the only thing we can think of is the JVM.
I've never encountered this type of problem before, so as I said, any help would be greatly appreciated.
